Atomfall isn’t a long game by any means, but if you’re hoping to explore every nook and cranny, and uncover every secret, you’ve got your work cut out for you. The game has an abundance of keys, locked doors, and hidden caches to discover, and one of the first you may run into is the Concrete Shelter Key.
The Concrete Shelter Key, which can be acquired by trading with Molly in Slatten Dale, doesn’t seem like it leads anywhere important. However, this particular key provides access to an underground network of tunnels that you’ll likely want to use later on in your game. Without further ado, here’s where to use the Concrete Shelter Key in Atomfall.
Where to use the Concrete Shelter Key in Atomfall
The Concrete Shelter Key can be acquired from Molly in Atomfall, by trading some items with her for it. Its description states that it can open a concrete bunker door in Slatten Dale, but where exactly?
Well, fortunately, this particular Concrete Shelter is right beside Molly. If you go up the hill from her, following the stone path, you’ll soon come to the small stone shelter it can be used on. There’s also a note on the door from Molly, stating that she’s been here, and you can get the key from her.
Unlocking the Concrete Shelter Door gives you passage to the Sewer Tunnels, which are one of many ways you can traverse Atomfall’s map. If you’re here early on in your game, you can use the tunnels to gain quick passage to Wyndham Village!
There are more entrances to the Sewer Tunnels scattered throughout the map, and it appears as though routes between different areas will unlock as you progress or discover more Keys.
